Timing is Everything: ISB Study Finds Link Between Bowel Movement Frequency and Overall Health

Everybody poops, but not every day. An ISB-led research team examined the clinical, lifestyle, and multi-omic data of more than 1,400 healthy adults. How often people poop, they found, can have a large influence on one’s physiology and health.

Autoimmune Disease and Pregnancy: ISB Study Challenges Prevailing Wisdom, Unveils Nuances

An ISB-led study showed nuanced pregnancy outcomes for pregnant individuals with autoimmune disease. The findings reinforce that there isn’t a one-size-fits-all approach, and provides important new avenues for further investigation.

Building a Better BMI

ISB researchers have constructed biological body mass index (BMI) measures that offer a more accurate representation of metabolic health and are more varied, informative and actionable than the traditional, long-used BMI equation. The work was published in the journal Nature Medicine. 

Risk Factors for Severe COVID-19 in Hospitalized Adults Differ by Age

A just-published study provides new information about which hospitalized COVID-19 patients are most likely to need mechanical ventilation or to die. The ISB-led work shows that vital signs and lab results at the time of hospital admission are the most accurate predictors of disease severity, more so than comorbidities and demographics.

Predicting ‘Long COVID’ At Initial Point of COVID-19 Diagnosis

Researchers have identified several factors that can be measured at the initial point of COVID-19 diagnosis that anticipate if a patient is likely to develop long COVID. They also found that mild cases of COVID-19, not just severe cases, are associated with long COVID. Their findings were published by the journal Cell.

Maternal COVID-19 Infection Increases Risks of Preterm Birth, Low Birth Weight and Stillbirth

An ISB-led study examined the electronic health records of more than 18,000 people with SARS-CoV-2 tests during pregnancy, and found that those who contracted COVID-19 while pregnant were more likely to have poor birth outcomes including preterm birth, small for gestational age, low birth weight, and stillbirth. 

Nir Barzilai on Health Span, Life Span and the New Science of Longevity

Longevity and aging researcher Dr. Nir Barzilai participated in a fireside chat conversation with ISB Co-founder and Professor Dr. Lee Hood. The two renowned scientists talked about Barzilai’s study of 750 centenarians, how aging research has changed over the years, and what exciting developments are coming. 

Microbiome and weight loss

Can You Lose Weight? Ask Your Microbiome

The strongest associations with weight loss success or failure – independent of BMI – are found in the genetic capacity of the gut microbiome. These new findings open the door to diagnostic tests that can identify people likely to lose weight with healthy lifestyle changes and those who might need more drastic interventions.

Metabolic Changes in Plasma and Immune Cells Associated with COVID-19 Severity, May Predict Patient Survival

Researchers from Institute for Systems Biology (ISB), Fred Hutchinson Cancer Research Center and other organizations have uncovered underlying metabolic changes that regulate how immune cells react to COVID-19. These findings are associated with COVID-19 severity and may predict patient survival. The work was published in the journal Nature Biotechnology.

Overall composition of gut microbiome in participants

Variations in the Microbiome Associated with Health, Disease

ISB researchers examined the associations between the gut microbiomes of about 3,400 people and roughly 150 host characteristics. The team looked at diet, medication use, clinical blood markers, and other lifestyle and clinical factors, and found evidence that variations of the gut microbiome are associated with health and disease.

Bacterial tug of war between prevotella and bacteroides -- gut microbiome

It’s ‘Either/Or’ for Two Common Gut Microbiome Genera, and Switching Teams Is Tougher Than Expected

There is a dichotomy between Bacteroides- and Prevotella-dominated guts — two common gut bacterial genera — and there is a significant barrier when it comes to transitioning from one to the other.

Mysteries of Cell Fate Unlocked with New Measurement and Modeling Techniques 

In the cellular process of differentiation, information about the concentrations of an important class of proteins residing in a cell’s nucleus has been lacking, a missing link needed for scientists to fully understand how the process works. ISB researchers have quantified this important class of proteins that play a key role in the formation of red blood cells.

How Old Are You? Your Body Might Disagree With That Answer

Researchers at ISB harnessed deep molecular and physiological information to determine an individual’s biological age, which they found was reflective of overall health compared to chronological age. The findings were published in the Journals of Gerontology: Series A.

Using Blood to Predict Gut Microbiome Diversity

Predicting the alpha diversity of an individual’s gut microbiome is possible by examining metabolites in the blood. The robust relationship between host metabolome and gut microbiome diversity opens the door for a fast, cheap and reliable blood test to identify individuals with low gut diversity.

ISB Engineer Hopes to Save the Sword Ferns in Seattle’s Magnificent Forest

Seattle’s Magnificent Forest at Seward Park is located within one of the nation’s most diverse neighborhoods. The 98118 zip code in southeast Seattle is home to people of all socioeconomic classes including groups of immigrants who speak more than 60 languages. Seward Park serves as an urban oasis for the community to enjoy nature, easy hikes, and access to the expansive Lake Washington. The park’s Magnificent Forest, so called because…

NIH Research Matters features ISB’s MTB paper

NIH Research Matters published an article on our tuberculosis paper. “The incredibly large number of possible drug combinations taken together with the difficulty of growing Mtb in the laboratory make discovery of effective combination therapy extremely challenging,” Dr. Nitin Baliga says. “We hope that our systems-based strategy will accelerate TB drug discovery by helping researchers prioritize combinations that are more likely to be effective.” READ THE ARTICLE
